A man is never more truthful than when he acknowledges himself a liar.
Mark Twain
When the got to Anakin and Ben's home (which was no more than a hut), Ben jumped out of the speeder, shouted a few instructions at Anakin, and pulled Qui-Gon into the house. After a quick greeting toward Ms. Shmi Skywalker, Ben guided Qui-Gon toward a room that was isolated from the rest of the hut.
"Now," he said, "I'm sure you have plenty of questions." Qui-Gon blinked. Ben must have sensed his surprise through the Force because he smiled kindly. "I live with Anakin Skywalker. I know how to tell when someone is practically bursting with unasked questions."
"You're a wizard?" said Qui-Gon. Ben's mouth tightened.
"That's the term the locales use, yes."
"And the term you use?" Ben turned away from Qui-Gon, as though afraid of his face giving away too much.
"I've lived on Tatooine for over twelve years. Before that, well, let's just say I'm not what the people here have fashioned me as. They created a name and I kept it. It was easier that way."
"You lied to them."
"A lie of omission is sometimes better than an unbelievable truth. Besides, this was the best way to restore my inner... balance." Qui-Gon narrowed his eyes.
"You live on Tatooine yet you speak like a cultured man. Why?"
"As I said, I haven't always lived here."
"Where did you live before?" Ben's head drooped just a tiny bit.
"Nowhere."
